Read with context.

Choose the geography and dataset before comparing values. Keep the population definition, data year and margin of error with every statistic.

A search result is not a finished finding. Read the table notes and confirm that compared groups use the same measure.

Limits to keep in view

Dataset coverage, release date and sampling uncertainty vary.

Connect evidence to action

Choose a question, verify the relevant jurisdiction, and explain the action you are asking someone to take. A source-backed draft is a starting point—not a message sent on your behalf.

Your working notes

Keep the context with the claim.

Write the question first

What are you trying to understand? Identify the population and place before looking for a number that might support your position.

Capture the measure

Record the source title, table or indicator, units, reference period and any stated uncertainty. Preserve the original wording of technical definitions.

Distinguish observation from explanation

A difference between groups can prompt further inquiry. It does not, by itself, identify the cause or establish the effect of a particular policy.
